Regular inspection of equipment; inspection of the bearings that were dismantled during work inspection and replacement of peripheral parts; it is better to judge whether it can be used or used again. It is necessary to carefully inquire and record the bearings and appearances that have been removed; In order to clarify and query the remaining amount of smoothing agent; sample the future; to remove the bearing well.
Secondly, check the raceway surface; the condition of the rolling surface and the cooperation surface, and the wear condition of the cage, etc., for damage and abnormal conditions.
Determine whether the bearing can be used again; consider the degree of bearing damage; machine function, importance, working conditions, viewing cycle, etc. to review the results in the future. Check the results; if the bearing is found to be damaged and abnormal; the contents of the injury section are identified Reasons; formulate countermeasures. Others; view the results; if there are several disadvantages; the bearings can no longer be used; the need to replace the new bearings.
a. Any one of the inner and outer rings, the roll body and the cage has cracks and fragments.
b. The inner and outer rings and the rolling body are stripped.
c. 1. The raceway surface, ribs and roll body have obvious card injuries.
d. The wear of the cage is severe or the rivets are loose and fierce.
e. The raceway surface, the rolling body is rusty and flawed.
f. There are obvious indentations and marks on the rolling surface and the rolling body.
g. Creep on the inner diameter of the inner ring or the outer diameter of the outer ring.
h. Overheating discoloration is fierce.
i. Smooth grease seal bearing seals and dust cover damage is severe.
(1), the inspection items in the work review and fault handling work have bearing tumbling sound, oscillation, temperature, smooth condition, etc.; the specific conditions are as follows:
First, the bearing's tumbling sound is selected by the sounder to check the size and sound quality of the rolling bearing in the working; even if the bearing has slight peeling and other damage, it will announce abnormal sounds and irregular sounds; .
Second, the bearing oscillation bearing oscillation is very sensitive to bearing damage; for example, shedding, indentation, rust, crack, wear, etc. will be reflected in the bearing oscillation measurement; therefore; after the selection of special bearing oscillation measuring device (frequency analyzer, etc. The large amount of oscillation can be measured. ü De Shi Zhi 豢 豢 鲆 鲆 鲆 5 5 5 5 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭.
